Embodiment 1

[0042] Weigh 15% diflufenican, 2% florasulam, 18% flufenacet, 9% lauryl polyoxyethylene ether phosphate, 3% phenethylphenol polyoxyethylene ether phosphoric acid Ester, 3% xanthan gum, 3% glycerol, 1% isothiazolinone, 1.5% butanol, deionized water added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sand-milled with a sand mill to prepare 35% diflufenican·flufensulam·flufenacet suspension concentrate.

Embodiment 2

[0044] Weigh 10% diflufenican, 3% florasulam, 7% flufenacet, 6% sodium lignosulfonate, 6% sodium alkyl polyoxyethylene ether sulfonate, 2% bentonite, 1 % polyvinyl alcohol, 3% sorbitol, 0.5% potassium sorbate, 1% octanol, and deionized water to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare 20% diflufenican·diflufensulam·flufenacet suspension concentrate.

Embodiment 3

[0046] Weigh 15% diflufenican, 2% florasulam, 18% flufenacet, 3% sodium lignosulfonate, 6% emulsifier BY-140, 4% agricultural milk 1601#, 2% Sodium alkyl sulfonate, 0.5% polyvinyl alcohol, 3% glycerin, and rapeseed oil are added to 100% by weight. The above-mentioned raw materials were mixed, dispersed at high speed for 30 minutes, and sand-milled with a sand mill to prepare 35% diflufenican·flufenacet·flufenacet dispersible oil suspension concentrate.

Abstract

The invention discloses a ternary weeding composition containing diflufenican and application thereof. The effective active ingredients are prepared from a first active ingredient of diflufenican, a second active ingredient of florasulam and a third active ingredient of flufenacet; the mass ratio of the three ingredients is (1 to 90):(1 to 90):(1 to 90), is preferably (1 to 60):(1 to 60):(1 to 60), is further preferably (1 to 30):(1 to 30):(1 to 30) and is most preferably 15:2:18. The composition can be prepared into agriculturally allowable suspensions, dispersible oil suspensions, wettable powder and water dispersion particles. The ingredients are reasonable; the weeding effect on broad leaved weed in cornfield is good; the active and weeding effects are not simple addition of activity of each ingredient. Compared with the existing single preparation or two-ingredient compound preparation, the ternary weeding composition has the advantages of obvious weeding effect, obvious synergized action, reduced pesticide consumption, wide weeding spectrum and low prevention and control cost.

Description

technical field [0001] The invention relates to a ternary herbicidal composition containing diflufenamide, which consists of active ingredients diflufenacet, diflufenacet, flufenacet and auxiliaries, and belongs to the technical field of compound pesticides. Background technique [0002] Diflufenican, the English name is diflufenican, and the chemical name is: N-(2,4-difluorophenyl)-2-(3-trifluoromethylphenoxy)-3-pyridineanilide. The application of diflufenican before and after weed germination can form a leaching-resistant medicinal soil layer on the soil surface, and maintain activity throughout the crop growth period. When the weeds germinate and pass through the medicinal soil layer, the young shoots or roots can absorb the drug. This agent has the effect of inhibiting the biosynthesis of carotenoids. The content of carotenoids in the weed plants that absorb the drug will decrease, resulting in the destruction of chlorophyll, rupture of the cell membrane, and miscellaneo...
